The small increase in typing is a small price to pay for much more reliable code.

Re: [Tutor] import of source code still not working
The problem here is that you need to reference the factor30 namespace to get to your functions: Your calls to your functions would then look like: factor30.factor(109) & factor30.factor0(109) If you don't want to have to put the factor30 in front of all your function names you can do this: from factor30 import * Which will put all of your functions into the global namespace. Then you can call factor() & factor0() as you would expect to.
